These are DNV approved corrosion resistant double t-bolt clamps. They are constructed from top quality 316L marine-grade stainless steel components with silver-plated nuts. They provide excellent sealing capability when used with marine silicone hoses, while offering great flexibility as a general purpose clamp.
Suitable hose diameters are listed below, while the height of the clamp is 19 mm and the thickness is 0.9 mm. This can make it easier to fit the clamps in situations where there is limited access.
